Everything about air conditioners in Astana
How to choose the right AC for an apartment, bedroom, office or house, how much installation costs and when cleaning is actually needed.
1
How to choose an air conditioner by room size
A simple baseline that works in most real cases.
The key reference point is cooling power in kW. For quick residential estimates you can use 1 kW per 10 m². But floor level, ceiling height, sun exposure and usage scenario also matter.
This is where people most often make mistakes when they search for an AC unit in Astana and want to avoid overpaying. Units may look similar, but their power, noise level and service life can be very different.

Tip
A small reserve in power is usually better than sizing the unit too tightly. It helps the system work more calmly and last longer.
2
Inverter or regular on/off
A practical comparison without marketing fluff.
If the AC will run often and for long periods, an inverter is usually the better choice. If usage is rare and the budget is strict, a regular on/off model can still make sense.
Inverter
from 150,000 ₸per unit
- 30–40% lower electricity use
- Quiet operation — from 19 dB
- Keeps temperature more stable
- Longer service life — 12–15 years
- Can heat down to −20°C
Regular (On/Off)
from 80,000 ₸per unit
- Lower purchase price
- Simple repairs and easier parts
- Uses more electricity
- Louder in operation
- More limited heating mode
If the system will work more than 4–5 hours a day, an inverter usually pays off through comfort and power savings within a couple of seasons.
For bedrooms, kids' rooms and offices, inverter units are usually the better choice because they are quieter. For occasional use, a regular on/off model may be enough.

Air conditioner installation in Astana
What installation includes, how much it costs and where people most often go wrong.
Standard installation includes mounting the indoor and outdoor units, laying the line set, connection, vacuuming and system startup. In straightforward cases it usually takes 2–4 hours.
If you need a turnkey install, discuss the line length, outdoor unit position and facade access in advance. Final cost often changes exactly at that stage.
| Service | Price | Note |
|---|---|---|
| Standard split-system installation | from 25,000 ₸ | Line up to 3 m |
| Installation with longer line set | from 35,000 ₸ | Up to 6–8 m |
| High-rise building installation | from 45,000 ₸ | Above 5th floor |
| Old AC dismantling | from 8,000 ₸ | Without disposal |
Important
Poor installation often leads to leaks, pressure loss and compressor issues. It is better to do it right once than to fix cheap shortcuts later.

Cleaning and maintenance
When filters are enough and when you need a technician.
Without regular cleaning, an AC loses power, starts smelling, gets noisier and cools worse. Maintenance matters not only for comfort, but also for the lifespan of the whole system.
If you notice a stale smell, water drops from the indoor unit or weaker cooling, you usually need full AC cleaning, not just a quick filter rinse.
DIY filter cleaning.
Remove the filters, wash them with warm water, dry them and put them back. It usually takes about 10 minutes.
Professional cleaning.
A technician cleans the heat exchanger, drainage system and indoor unit. Best done before the season starts.
Deep maintenance.
Full disassembly of the indoor unit, fan wheel cleaning, refrigerant pressure check and contact inspection.

Refrigerant recharge
When it is really needed and why topping up blindly is a bad idea.
In a healthy system refrigerant does not get used up by itself. If cooling drops, the first step is to find the actual cause.
Typical signs: the AC runs but barely cools, frost appears, noise increases or energy usage climbs.
If cooling performance dropped, do not rush to order only an AC recharge. It is smarter to diagnose the system first and confirm that refrigerant is really the issue.
| Service | Price |
|---|---|
| Refrigerant pressure diagnostics | from 3,000 ₸ |
| R32 / R410A recharge | from 12,000 ₸ |
| Leak detection and repair | from 8,000 ₸ |
Tip
Recharge without finding the cause is often wasted money. If there is a leak, the problem will come back quickly.

Common mistakes in choice and use
This is where comfort and money are usually lost.
Choosing a unit with no power reserve
The system constantly works at its limit and wears out faster.
Ignoring filter cleaning
Air quality drops and electricity use goes up.
Placing the outdoor unit badly
Direct sun or poor airflow causes overheating.
Setting the lowest temperature immediately
Extreme temperature differences are not ideal for comfort or equipment life.
Not checking the installer
Saving on installation can easily turn into an expensive repair later.
It is usually better to understand the room scenario first and only then compare actual series in the AC catalog.

Frequently asked questions
Short answers to the most common doubts before purchase and installation.
Is an air conditioner the same as a split system?
In everyday use, yes. Split system is simply the technical term for a unit with indoor and outdoor blocks.
Can I use an AC in winter?
Inverter models often work in heating mode down to −20°C and lower, while regular models are usually more limited.
How long does installation take?
A standard install in an apartment usually takes 2–4 hours. More complex cases can take up to 6 hours.
Do I need approval to install one in an apartment?
Usually no, although some buildings or management companies may have facade rules.
My AC is installed but not cooling well — what could it be?
Most often it is dirty filters, refrigerant loss or a pressure-related issue. If the filters are clean, diagnostics are the next step.
Can the outdoor unit be placed on a balcony?
On an open balcony, yes. On a closed balcony, it is usually a bad idea because airflow is restricted.
If you want a fast selection logic
First define the room size and scenario, then compare brands, series and installation cost. That usually gives a much better result than picking by appearance alone.
